Our expert says:
the symptoms your grandmother are experiencing could be due to dementia (brain dysfunction) In old people this can be caused by simple and treatable things like low levels of potassium in the blood or vitamin deficiency or medication side effects. In a small percentage of cases this is caused by repeated small strokes of the brain or Alzheimer's disease. Please take her to a doctor so that they can test her blood to see if she has enough salts and vitamins in the blood, to evaluate her medication and if needed to refer her to a neurologist for evaluation. If she has brain damage due to small strokes or Alzheimers they can prescribe something she can take to stay calm and be less agressive.
